I have a 2012 R2 WSUS server, and many 2012 R2 clients.

One of my servers only, completed installing a batch of updates, and now upon every check for updates, it gets stuck "Checking for updates".

The last entry in the WindowsUpdate.log file is as below:

Wsus reports 4 updates needing to be installed on the server, so I am expecting the client to return that information, and attempt to install those 4 updates.

I have tried running the Windows update trouble shooter, which found two issues and fixed them. I restarted several times, to no avail.

I also tried removing the software distribution folder and retrying, but no change.

I am now running an sfc /scannow now, as well as some DISM /scanhealth and restorehealth commands to check for issues.

Is there anything else I can check to determine why WU forever sits checking for updates? My other servers are all ok.

    WARNING: There are no approved updates to install - Have you made sure these updates are approved? Have you checked to see if these updates are hidden on the server?

    The updates are indeed approved. If I run a report against this server, it lists 2 flash security updates, and 2 updates for Windows Server 2012 R2. All have approval status of Install, and status of not installed. I have installed these on other servers today without issue. Dec 14, 2016 at 16:57
  • I just ran the troubleshooter again, and it looks to report the same issues again (Service registration is missing or corrupt, and problems installing recent updates), even though the troubleshooter reportedly fixed these on the last run. Should I run through the whole reset process for the update components: support.microsoft.com/en-gb/kb/971058 Dec 14, 2016 at 17:04
  • Are those updates downloaded to your wsus server? They might be approved but not on the server yet and thus won't install. Add a column to wsus to show that. Do those updates depend on other updates?

  • The updates are downloaded, as I have installed them on other servers. They do depend on two prior updates, both of which are installed. Dec 15, 2016 at 11:58

Server finally showed me some updates after 2 days of "Checking for updates" and a server restart.
